Tutorial quote: In this note we shall talk about installing FreeBSD on a very interesting and elegant machine: IBM Netvista S40. In its creator own terminology, it is "legacy-free". The computer has no parallel, serial, AT keyboard, nor PS/2 mouse ports. No floppy controller either. Instead, it has 5 USB ports (2 frontal and 3 rear) connected to a single USB controller. Besides these USB ports, the system only counts with standard video and audio connectors. The video controller is Intel 82810E SVGA and audio chip is Intel ICH 82801AA, both integrated onboard. The CPU is Intel PIII at 866MHz. The machine is further equipped with a fast Intel Pro PCI network adapter containing a PXE/RIPL boot prom. A quiet 20G Quantum Fireball HDD and a Liteon ATAPI CD-ROM, both connected as masters, constitute the storage subsystem. The case is Flex ATX, a small form factor.
